agree with M @ T, except I think the + might go higher, maybe 100k+? 15/7 tact shields are really popular right now. While it's not the fanciest/rarest skin, it's usually considered nice looking, so I can see how the skin will raise rather than hurt the price.

EDIT - oops, forgot the blue! So 100k+ could be a little high.
[email protected] was probably closer with 80k+ My bad, apologies.
